The Technology: Adaptable nanosensor for time-resolved detection and monitoring of biomolecular analyte.
This technology is an aptamer-based graphene nanosensor that enables real-time detection and characterization of biomolecular interactions.
Upon selective analyte enrichment and aptamer binding, the conductance of the graphene nanosensor changes and delivers an accurate and real-time electrical readout of the analyte activity.
